A method for configuring and/or correcting misconfigurations within a clustered network includes determining, at each node of multiple nodes in the clustered network, configuration data that identifies a connection type between the node and at least one device connected to the node, where the connection type is either a switched or switchless connection. The method further provides for publishing the configuration data determined at each of the multiple nodes to a location mutually accessible by other nodes in the clustered network generating a map of physical network topology of the clustered network based on the published configuration data; using the map of the physical network topology to determine a correct logical layer configuration for the network; and configuring one or more aspects of the network to match the determined correct logical layer configuration.
Legal claims defining the scope of protection, as filed with the USPTO.
6. The method of claim 5, wherein the LLDP frame received from each device identifies a chassis ID, and wherein generating the map of the physical network topology further includes using the chassis ID associated with each device to identify a subset of the multiple nodes coupled to a same switch.
10. The system of claim 9, wherein the endpoint investigator determines that the clustered network is a switched network and the correct logical layer configuration is a configuration in which each subset of network interface controllers (NICs) connected to a same switch is configured to share a common internet protocol (IP) subnet and virtual local area network (VLAN).
13. The system of claim 12, wherein the endpoint investigator is further executable to determine that the select is a switch rather than a node responsive to determining that the port ID in the LLDP frame of a select device connected to the node does not match any of the MAC addresses received by the node.
14. The system of claim 10, wherein the LLDP frame received from each of the one or more other devices connected to the node identifies a chassis ID and wherein the map of physical network topology connects a subset of nodes sharing the chassis ID to a same switch.
15. The system of claim 9, wherein the configuration diagnostic tool is further executable to use the map of the physical network topology to identify a misconfiguration within the clustered network and to alter a logical layer network setting to correct the identified misconfiguration.
